Demonstration of Non-Orthogonal Pilot Multiplexing for Continuous-Variable Quantum Key Distribution
Hong Yang, Amirhossein Ghazisaeidi, H. Mardoyan, Jérémie Renaudier · 2025
We propose and experimentally demonstrate non-orthogonal pilot multiplexing for CV-QKD, which requires no additional time/frequency/polarization resource whilst effectively reducing receiver’s DSP complexity. ~53.35-Mb/s average secret key rate over a channel loss of 5dB is achieved.
